This happened to me with redline oil. I usually use nissan ester which doesn't have the white foam piece. I poured 5.2 quarts then the next day added a bit more and the white foam piece was stuck to the top of the bottle and fell out as I poured oil. Luckily, I do use a funnel that has a small neck.
